Science Trick

the positve and negative magnetic fields push against one another. Try pushing two magnets against each other on a table. One side of each magnet is positive, the opposite side negative. Positive will attract negative, while opposites repel. When they repel, they will slide away from each other without touching.

wat are the things used
magnet , ....?

ive seen this before, if i remember right its a material that becomes magnetic at extremely low temperatures.

Sounds like you guys should be working at Area 51!

well thats nitrogen which is supper cold and the black thing is a magnet the metal is coper if you freeze the magents and put a piece of cooper thast what u get cause the cold messed the gravity pull!! or u can have a cope plate on a OLD disk player sping it around and put a magnet on top and it floats.

If held upside down it will do the same thing.

I KNO! Its has sumthin to do with sience!! lol

Superconductivity Experiment with YBaCuOx (123) or may be BiSrCaCuOx (2223) Vlad Fotiyev:)

awesome

that is pretty cool ive never seen anything like that
